Prone to sinus infections due to allergies - how concerned should I be about developing capsular contracture?

Once your allergies develop into a bacterial infection, some of that bacteria could go to one of your implants and develop a capsule or even a frank infection. You do need to be on antibiotics for your infection in your sinuses and to protect your implants. If you are just having allergies or a viral infection, you have less worry.

Having seasonal allergies and sinus infections does not mean you will develop capsular contracture. There is much that we are still learning about the development of capsular contracture. There are certain precautions that are taken to minimize the risk. Keeping touching of the implant to a minimum during augmentation surgery, and using antibiotics and antibiotic solution during surgery are just a few. I've included a video that I hope you find helpful.

Fortunately you have saline implants which rarely encapsulate. The other issues you have should not affect capsular contracture in any way
